    It can't hurt to try using the "add features" route. I know my TechNet "Retail" Pro keys are accepted.

However during install I am normally prompted to enter my Serial for 8.1 and it does not do this. It progresses as though everything is ok, I can format the Hard drive and then it proceeds to install Windows 8.1.

    Once fully installed I then go to see if it is activated and to my surprise it is. It has activated with the same Serial as the OEM that came with the laptop.
    Upgrade from Windows 8.1 to Windows 8.1 Pro with a Windows 8.1 Pro product key.

    Add Features to Windows 8

    8. If you Already Have a Product Key Number

    A) Enter your product key number of the feature or edition that you purchased, wait for the key to be approved, click/tap on Next, and go to step 10 below. (see screenshot below)

    You can use this option to do either of this below:

    • Add the Windows Media Center feature to Windows 8 Pro or Windows 8.1 Pro.
    • Upgrade from Windows 8 to Windows 8 Pro with a Windows 8 Pro product key.
    • Upgrade from Windows 8.1 to Windows 8.1 Pro with a Windows 8.1 Pro product key.

    Thanks for your help guys. This fixed my issue. Bit of a pain but hay ho we live and learn

    It makes it a two step process, but at least its doable. I had to go that route when I was running 8.0 on my laptop. It was three steps for me as I also added Media Center. Windows 8.1 ignores the 8.0 embedded key so now I can go right to Pro. I use USB thumb drives to install Windows so I just add a PID.txt file to them. I add some OEM info too. I have one install thumb drive for each PC I own. I do everything from thumb drives these days. The only time I touch an optical disk is to install games with DRM.
